I'll answer both of you here ... System Restore has its uses, but not for me ... it is
not a cure all, that status goes to clean re-install of the OS.
I don't hold much faith in MCrapFee either, however, I think you are a "victim" of Dell's crud they install ... their "helpfulness" on what they install in their system is mindboggling crap.
Do you also have a Dell printer, I now suspect this is a remnant of their drivers ... now I know that it was a typo you made with the m & e ...
I just tried to download Regcure, but all I got was redirected to blank pages ... strange ?
As far as I can see Regcure should rid you of the invalid entry in the registry ... up to you as I have not "tested" it myself ... is it one of Dell's installed programs, or did you install Regcure ?
One program I can recommend is CrapCleaner ... does as it says on the tin with no adverse affects ... However, be careful on installing it as it will want to install Yahoo's toolbar, as you already have enough junk on your PC, just un-tick that particular box and carry on.
I can also recommend
This Program for any new Dell owner ... actually, it's a good program to have in any good techs toolbox.
Let me know how you get on ...
